Note: Estimates do not include youth who dropped out of school and therefore may not reflect total national percentages. 
1Sexually experienced is defined as ever having had sexual intercourse in one’s lifetime.
2Race/ethnicity estimates from 1999 and later are not directly comparable to earlier years due to federal changes in race definitions. In surveys conducted in 1999 and later, respondents were allowed to select more than one race when selecting their racial category. Estimates presented only include respondents who selected one category when choosing their race.
